ABSTRACT:
A heat shrinkable polymer material is particularly adapted for implanted biomedical use. A polycrystalline polymer is irradiated to produce crosslinking of its intramolecular structure to thereby impart viscoelasticity. The material is biocompatible and suitable for implanted use, from the standpoints of very low toxicity, ability to retain structural integrity and being non-carcinogenic and, moreover, is heat shrinkable at a temperature compatible with such implanted use.
